tensorplay.nn.functional.unfold(input, kernel_size, dilation=1, padding=0, stride=1)[[source]](../_modules/tensorplay/nn/functional.html#unfold)

Extract sliding local blocks from a batched input tensor (torch
F.unfold, i.e. aten::im2col).  4-D batched input is the common case;
unbatched 3-D input is accepted like aten’s im2col.
